WILSON E. SYMONS, OF CHICAGO, ILLINOIS.

RAILWAY BUMPlNG-POST.

Specification of Letters Patent.

Patented March 5, 1907,

Application filed October 31,1906. Serial No. 341,464.

To all whom it may concern:

Be it known that I, WILsoN E. SYMoNs, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented a new and useful Railway Bumping-Post, of which the following is a specification.

This invention relates more particularly to that class of bumping-posts disclosed in and covered broadly by a prior patent granted to me in November 14, 1905, and numbered 804,685, though there are features in the present invention unquestionably applicable to other types of posts.

One of the principal objects is to provide a structure having parts that can be more readily and conveniently cast, said parts when assembled preferably having a slight relative play or movement and yet constituting a thoroughly efi'ective apparatus for the purposes specified.

A further and important object is to pro vide a structure which is mounted on the rails of the track and is so braced that the rails and connections will not be closed or pulled toward each other when the posts receive a heavy blow or shock.

Still another object is to provide securing means for the post that can be readily applied to rails of different sizes and is so associated with the other parts that while the same are effectively connected thereto they may be readily detached if it is found convenient or necessary to do so.

The preferred form of construction is i lustrated in the accompanying drawings, where- 1n Figure 1 is a top plan view of a section of a railroad-track, showing the improved post in place. Fig. 2 is a front elevation of said post with the bracket-mountings in section. Fig. 3 is a side elevation of the structure. Fig. 4 is a longitudinal sectional view therethrough. Fig. 5 is a crosssectional view on the line 5 5 of Fig. 4. Fig. 6 is a detail sectional view on the line 6 6 of Fig. 4. Fig. 7 is a side elevation of one of the bracket-mountings with the pivotal connection of the associated arm illustrated in section.

Similar reference-numerals designate corresponding parts in all the figures of the drawings.

The present structure is applicable to a railway-track at substantially any point and is secured directly to the wheel-rails of the track. For this purpose bracket-mountings 8 are employed, having portions 9 that are arranged to fit against the webs of the rails, said portions being provided with vertical slots 10 to receive the fastening-bolts 11 passed therethrough and through the rails. hese brackets, furthermore, are preferably provided with spaced hooks 12, arranged to engage beneath the base-flanges of the rails, as shown. By having the slots 10 the brackets can be secured to rails of different weights or sizes, as shown in Fig. 5. In case of application to lighter rails, as indicated in dotted lines, shims 13 are introduced between the base-flanges and the brackets. These brackets are provided with upstanding hooks 14, forming journal-sockets 15, which are provided with contracted mouths 16 opening through the tops of said bracket.

A carrier member is employed comprising upwardly-convergent side arms 17, carrying at their upper ends a stem 18 and having the space between their lower ends bridged bya strut 19. A brace 20 connects an intermediate portion of the strut and the convergent ends of the arms. The carrier member is preferably cast in a single piece, and its lower wider end is provided with outstanding pintles 21, that are rotatable in the sockets 15 of the bracket. It will be observed by reference to Fig. 7 that these pintles are camshaped, so that their width in one direction is less than their width in another. The major axes of the pintles are disposed longitudinally of the side arms, and consequently when said side arms are at a rear inclination, as shown in Fig. 7, the pintles will be interlocked in the sockets and cannot be removed therefrom. Nevertheless if the carrier member is swung to a forwardly-inclined position the minor axes or narrower portions of said pintles will be alined with the contracted mouths 16 of the sockets, and consequently said pintles can be readily passed therethrough, so that the carrier member may be detached from the said brackets.

Associated with the carrier member is a car-engaging member 22, comprising a curved head having a socket 23 between its ends,

- which socket receives the stem 18 of the carrier member. A shoulder 24 is formed upon the rear side of the car-engaging member 22, just above the socket, and cars 25 are located on opposite sides of said socket and shoulder 24. The rear or upper end of the stem 18 of the carrier member is also provided with a shoulder 26, which shoulder is located between the cars 25 and in spaced and opposing relation to the shoulder 24. A key 27, passing through the ears 25, passes between the shoulders 24 and 26 and is suitably retained in position by pins 28 or other devices. In actual practice the various parts preferably do not fit snugly in order to allow slight play between them, as this is believed to be ad vantageous in the operation of the post.

The upper end of the car-engaging member or head 2 has a dovetail socket 29 formed in its front face to receive a suitable buffer 30, preferably of wood, which buffer is at a sullicient height to engage the carbody. The opposite or lower end of the car-engaging member or head 22 is provided with a series of sockets 31, and a base 32 is located beneath the same and has similar sockets 33 in its upper side. Springs 34 are located in said sockets, and thus serve to yieldingly support the car-engaging member or head. The base 32 is suitably secured to beams 34, arranged longitudinally between the rails and bolted to the ties 35 of the track. The base 32 is furthermore preferably provided with upstanding guide elements 36, located on opposite sides of the car-engaging member or head and provided with longitudinally-disposed guideways 37. The lower end of the head has outstanding lugs 38, that slidably engage in these guideways, their upward movement being limited by transverse stop bolts or pins 39, carried by the upper ends of the guide elements and extending across the upper ends of the guideways 37, as shown. So far as the yielding mounting of the head or car-engaging member is concerned it is substantially the same as that disclosed in the prior patent, of which mention has already been made.

It will be noted that this structure can be applied to a track at substantially any point desired, and, as already shown, the brackets are attachable to all grades of rails. The parts can be readily cast and easily assembled, being held together by a very substantial connection which admits of some little flexibility or play. The particular construction of the carrier member or frame is important, for by providing the cross strut or brace there is no danger of the side arms, and consequently the rails, being drawn toward each other when the post receives a heavy blow or shock. I11 this structure, furthermore, the parts can be easily disassociated, if it is de sired to remove the post, for it will be evident that the head can be readily detached from the carrier member and that the carrier member may be removed from the brackets by merely swinging the same to a forward posi tion, so that the pintles may be passed through the throats 16 of the sockets 15.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art Without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.
